Abstract: Air conditioner for vehicle, small and having two independent air flow paths, controlling air volume independently for each air flow path, and can remove noise while regulating the air volume corresponding to the desired flow path through means for returning flowing air toward a suction port. The air conditioner for vehicle comprises a blower having a plurality of blower wheels, and one blower motor for driving the plurality of blower wheels with the same force, a plurality of inlet flow paths allowing an air inflow port to communicate with a blower inlet, and a return flow path which has a plurality of outlet flow paths allowing a blower outlet to communicate with an air discharge port, which returns, to the blower inlet, at least a part of the air discharged from the blower outlet so that the air volumes discharged from the plurality of air discharge ports are regulated differently.
